Ambient lighting LED specification

So, I'm sorry if this had been asked before but I'm on my phone so I don't have much search capability.

What mcd and lumen specification (and possibly angle, but I'm guessing it's 8-15 degrees) LEDs are used in the overhead console ambient lighting for pretty much every VW and Audi recently? I'm working on a project to add it to my car but I have no idea what to buy, I don't want them too bright. Thanks!

As a side note, if anyone knows anything about the specifications for LEDs in the switches of a 3.5 cabrio, that would also be appreciated!
